Mav, it's not just my opinion. It's fact.
link Ethanol as a fuel is nothing new. Dan Sperling, a professor at the University of California at Davis and director of its Institute of Transportation Studies, noted that even early Model T Fords used ethanol, and it's an ingredient in beer and wine.
Most ethanol produced in America is made from corn -- a less-efficient material than switchgrass -- but corn producers are supported by a large lobby and huge government subsidies. There is no similar lobby or investment for grass or wood.
"When you make ethanol from corn, for every gallon of fuel you get, you put in about seven-tenths of a gallon of fossil energy, oil or natural gas," he said. "That's only a small improvement in terms of greenhouse gases."
On the other hand, he said, "ethanol from cellulose [like switchgrass] is a great energy strategy because for every gallon of ethanol, a tiny amount of fossil material [is used.] There's a dramatic reduction in greenhouse gases, so from an energy perspective it's far superior."
"We've known this for a long time," Sperling said. "Why has nothing happened? Part of it is we do need more R and D [research and development], but I think what we really need is a commitment on the industry and business side to invest."
